We discussed what amount the offer should be, strategy on how to handle a potential counter offer, etc. and then I told him on Saturday afternoon to go ahead and write up the offer for the amount we've agreed upon.

Any bank with more than a single branch has a loss mitigation department with a specialist that uses modelling to review/accept/counter offers.

That's crazy low and doesn't account for rehab overages, reasonable counteroffers against your asking price, deal falling through a few times, etc.Never think you're different, or that you can somehow get around profit equaling income minus expenses.

Greetings fellow BP membersI jumped into the deep end and have just accepted a counteroffer on my FIRST fix/flip in colorado (teller county). 

When written offers are made to realtors in Florida, are there any requirements that they provide a written response from the seller indicating that the offer was rejected or a counter offer made?

UPDATE: The bank counter offered and is asking for $45k, $1,000 earnest money and closing by February, 15th.

Should I send in a counter-offer and cancellation contract at the same time?

My realtor has always checked the backup offer option and I have never been awarded a house based on that - even if my offer was MORE than their counter offer.

I've had deals where the seller countered with a slightly lower price and my counter offer would be the exact same as the first. even if it's been on the market for 2-3 months, has the seller been aggressively dropping the price or has it been 400k for the duration?

If integrity is in question it should be a two way street.When buyers put in highest and best offers and agent comes back looking for more if we assume buyers have integrity there would be no counter offers.
